[PATCH 0/2] difftool --dir-diff: symlink all files matching the working tree

Here's the proper patch.  It grew into a series because I noticed a
minor formatting error in the difftool documentation, which the first
commit fixes.

The content of the second patch is the same as was previously posted.
